CONSTRUCTION OF CHIMNEYS.

Specification of Letters Patent. Application filed September 15, 1909.

Patented Oct. 18, 1910. Serial No. 517,774.

To all 'whom 'it may concern:

Be it known that I, ALFRED XV. FLETCHER, a citizen of the United States,and residing at Brooklyn, in the county of Kings and State of New York,have invented certain new and useful Improvements in the Construction ofChimneys, of which vthe following is a specification, vsuoli as willenable those skilled in the art to which it app'ertains to make and usethe same.

This invention relates to the construction of chimneys of various kindsandclasses and particularly to the-- chimneys of residences and theinvention involves an attachment for chimneys of this class designed topre vent water or moisture from or in the top portion of the chimneyfrom passing or seeping through the roof construction around the chimneyand discoloring the chimney breast within the rooms or compartments ofthe building.

The invention is fully disclosed in the following' specification ofwhich the accompanying drawing forms a part, in which t-he separateparts of my improvement are designated by suitable reference charactersin each of the views and in which Figure 1. is a sectional view of thepart of the roof construction of a building and showing, in section, thetop portion of a chimney with my improvement applied. Fig. 2. asectional View of the chimney and my improvement at .rightangles to thatshown in Fig. l, and Fig. 3. a plan view of my improvement detached fromthe chimney.

The sectional view shown in Fig. l cuts my improved attachment on theline of Fig. 3 and the sectional View shown in Fig. 2 cuts theattachment on the line y-y of Fig. 3.

In the drawing' forming part of this invention I have shown at a a partof the roof construction of a building comprising one of the usualrafters a2 and the usual sheathing a3, over which is placed the shinglesat.

I have shown at Z) a part of an ordinary chimney, and at c the lashingswhich are placed around that part of the chimney immediately above theroof and which are provided at their upper edges with flanges c2 whichare inserted into the chimney construction at a predetermined pointabove the roof and the bottom edges of which are provided with flangesc3 which extend out over the roof construction and which are designed toprevent water passing down over the roof'from entering the buildingaround the chimney. y

In the practice of my invention I provide a. chimney attachment ordevice d, a plan view of which is given in Fig. 3 with part of theconstruction broken away and sectional views of which as applied to achimney are given in Figs. l and 2. In the construction of the chimneythis attachment is applied transversely thereof directly over theflashing c as clearly shown in Figs. l and 2 and the said attachmentcomprises a base or body plate (Z2 of copper, brass or other suitablematerial which will not corrode or be destructibly alleeted by moisture,said plate being provided with a downwardly directed flange (Z3 whichoverlaps the y ashings c.

The chimney l) shown in the drawing is provided with two ilues b2 andthe attachment l or the main or base plate (Z2 thereof is provided withcorresponding openings b3 around which are upwardly directed flanges orcollars Zt and the base plate (Z is also provided on the top thereofwith transversely and longitudinally arranged bars e whichextend to theouter edges of the side and end portions of the attachment and areprovided with upwardly directed projections e2, and the plate Z2 is alsoprovided, in the form of construction shown, and on the corners thereofwith radially arranged bars e3 similar to the bars e but the outer endportionsl of which are not provided, in the form of construction shown,with upwardly directed projections e2.

Then the attachment has been placed in position, as shown in Figs. l and2, the top portion 54 of the chimney is built up thereon as clearlyshown and in such manner as to form an extension of the fines b2 abovesaid attachment and in practice the top portion of the chimney above theattachment d may be made of any desired height.

In building up the top portion of the chimney 64 on the attachment d,the ues b2 are made slightly larger than said fines below saidattachment whereby narrow spaces 7 are formed around the flanges orcollars d4, the object of this construction being to enable any water ormoisture which may enter the tops of the ues b2 above the attachment topass between the walls of said fines and the flanges or collars Z4 andfall onto the base or body plate cl2 of the attachment and run off inthe spaces between the bars c and e3, it being understood that inbuilding up the top portion of the chimney above the attachment thebricks of the chimney Wall are laid on the bars c and e3, and thisconstruction forms a thin open space or spaces between the top portionof the chimney and the base or body plate Z2 of the attachment intowhich all Water or moisture which enters the chimney at the top, orwhich collects on the top portion of the chimney, or in the materialthereof will flow and this Water or moisture will also flow down overthe flange d3 of said attachment and over the lashings c as will bereadily understood and no Water or moisture Will be permitted to passthrough the roof construction at the point Where the chimney passesthrough. I also provide a cap g which may be placed on the flange orcollar d* of either of the flues Z22 when said flue is not in use andthe cap g is provided with a central opening g2 having an upwardlydirected flange or collar g3 and this cap when constructed in thismanner permits a free ventilation of the chimney through the flue towhich it is applied and may be removed or detached when it is desired touse said flue.

It will be apparent that my improvement may be applied to a chimney ofany number of llues and a cap g may be applied to any number of saidliues and, in practice, all the parts of the attachment as Well as thebase or body plate cl2 thereof are made of metal Which will not corrodeor be destructibly affected by moisture.

I-Iaving fully described my invention what I claim as new, and desire tosecure by Letters Patent is 1. An attachment for use in chimneyconstructions, said attachment being adapted to be placed transverselyin a chimney over the roof construction a'nd com rising a plate havingdownwardly directed flanges which overlap the flashing of the chimneywhen in use, said plate being provided with apertures or openings whichcorrespond With the lines in the chimney and around which are upwardlydirected flanges or collars, and said plate being also provided on thetop surface thereof with transversely and longitudinally arranged barsor raised members on which the top portion of the chimney may be laid.

2. The combination with a chimney construction of an attachment Which isplaced in the chimney transversely thereof and over the roofconstruction, and comprising a plate having downwardly directed flangeswhich overlap the flashing of the chimney, said plate being providedWith apertures or openings which correspond with the flues in thechimney, and around which are upwardly directed flanges or collars, andsaid plate being also provided on the top surface thereof with bars vorraised members on which the top portion of the chimney is laid.

In testimony that I claim the foregoing as my invention I have signed myname in presence of the subscribing Witnesses this Hth day of September1909.
